[PATCH v1 09/15] clk: qcom: dispcc-sdm845: convert to parent data

[Dmitry Baryshkov]

Convert the clock driver to specify parent data rather than parent
names, to actually bind using 'clock-names' specified in the DTS rather
than global clock names.

[PATCH v1 10/15] clk: qcom: gpucc-sdm845: convert to parent data

[Dmitry Baryshkov]

Convert the clock driver to specify parent data rather than parent
names, to actually bind using 'clock-names' specified in the DTS rather
than global clock names.

Convert the clock driver to specify parent data rather than parent

than global clock names.

Re: [PATCH v1 06/15] clk: qcom: videocc-sc7180: drop unused enum entries

[Taniya Das]

Hi Dmitry,

Thanks for the patch for cleanup.
It is okay to remove TEST source, but you can still keep the sleep clock 
source as it could be still connected to certain RCGs and could be used 
to derive low frequencies if required.

As these sources are generated from the HW plans it would be good if we 
keep them as they are except the TEST source.

Please note that I've barely removed the unused enum entry, which is
not used in any of clock parent maps. So I'd suggest to either add it
to relevant clock parent maps and to the videocc bindings or to drop
unused enum entry.

Is there a reason to resend the patches?
I'm not removing any actual clock sources, only unused(!) enum entries
are removed. No functional changes.

That's fine if we're just removing enums. I was hoping Taniya would
respond with a reviewed-by tag or at least to this thread so we know
everyone is OK.

These are supported from the design, please do not remove them. It is 
just that in SW currently it is not being used.
But SW can decide to use them as they want. As said earlier these are 
defined in the HW plans and thus do not want them to be updated manually 
to create a mismatch.

I see your point here. I'll drop these patches and refresh the
parent_data conversion patches.

The problem arises during conversion of these drivers to use parent_data 
instead of parent_names. You see, video_pll0_odd/_even are clocks which 
should be referenced using .hw (and thus defined inside the videocc 
driver) as we do for "video_pll0" parent. However there are no clk_hw 
entities defined for those clocks. For now I'd just use the { .name = 
video_pll0_out_odd" } entry for those clocks, however I still think this 
is not correct.

Yes we shouldn't be adding .name anymore. Can we add the
video_pll0_out_{even,odd} clks? Or if they're not used then can we
remove them from the parent_data and leave some sort of comment
indicating that they may be there?

Looks like in this case it would be OK because the array would be length
2 instead of length 5.

Downstream kernel provides no information regarding these clocks. I'll 
just leave them commented out (but inplace).
